TANGLE ARRESTER .FOB CONING MACHINES.

Application filed October 14, 1925. Serial No. 62,387.

In coning yarn for knitting machines by the usual method, the yarn comes from the spindles more or less defective by reason of loops, snarls or lumps which, in shop parlance, are designated as tangles. These tangles go to the cones and ultimately to knitting machines where they cause havoc with the needles.

The object of my invention is to provide simple and eiiicient means for arresting these tangles before they reach the cones.

This object, and other advantageous ends which will be described hereinafter, I attain in the following manner, reference being had to the accompanying drawings in which Figure 1 is a fragmentary end view, and

Figure 2 a fragmentary front view of a standard coning'machine, showing my tangle arrester attached thereto.

Figure 3 is a perspective view of my tangle arrester.

Coning machines are well known and only such description will be given as is necessary to an understanding of my invention. Each machine is adapted to wind yarn simultaneously from a plurality ofspindles onto an equal number of cones but, as all the w1nding units are alike and for the sake of clearness, a single unit will be described as 1f 1t were a complete machine.

The spindle, from which the yarn is to be .wound, is placed near the bottom of the machine .and the yarn led upwardly through a tensioning device under the trigger of a tripping mechanism, over a yarn rest, and onto the cone on which the. yarn is to be wound. The cone rests on a winding roller which causes the cone to rotate and wind the yarn thereon.

Should the yarn break, the trigger will fall and carry with it a hooked member which will engage a tripv arm. This trip arm oscillates continuously so that when the hooked member drops and engages it, a tripping mechanism is pulled forwardly in such a manner that the cone is raised out of contact with the winding roller, thus stop-.

ping rotation of the cone.

Referring to the drawings, 7 represents a fragment of the trip arm, which is mounted on a shaft 6; 9 the tripping mechanism, to which is attached the hooked member 13 carrying the trigger 14. Thewinding roller 21, which is mounted on shaft 19, bears against and actuates the cone 23 on which yarn 3etis evenly wound by being led through the end of a cam driven arm 20.

My tangle arrester consists of a back 24 from which a plurality of closely adjacent back in which the pins are fixed may be carried by afianged holder 26 having an arm 27 by which it may .be adjustably connected with an arm 28 by means of a clamping member 29 and bolt 30. Arm 28 is mounted upon a pivot pin 31, extending from the tripping mechanism, is made adjustable thereon by a set screw 32 and is so disposed that back 24 will be at an acute angle to the path of the yarn with the pins extending into that path and inclined in the direction from which the incoming yarn comes, as clearly shown in Figure 1. By adjusting the position of arm 28 on its pivot, the angle of the back 24 to the path of the yarn may be changed to bring a greater or less mun-- ber of the ends of the pins within the area of probable contact with the tangle. By loosening bolt 30, arm 27 may be swung relatively to arm 28 and thus-change the angle of the transverse rows of pins relatively to the path of the incoming yarn. The smaller the yarn, the greater should be this angle. Yarn guides 33 extend from the flanged member. In Figure 2, I have shown astrand of yarn 34 leading from a spindle (not shown) to cone 23 and having a loopformed tangle 35 approaching the tangle ai' rester. In Figure 1-, I have shown loop engaged with the arrester, and the yarn broken.

Any tangle upon the yarn will be caught by one or more of the numerous pins. This will cause the yarn to break. Hook arm 13, which has been supported by the yarn by means of trigger 14, will then drop by gravity and engage with trip arm 7, which is oscillating continuously, thereby moving trip member 9 forwardly, thus actuating the tripping mechanism which also lifts the cone out of contact with roller 21, the mechanism being so designed that it remains in this position until reset. The tangle is then eliminated and the broken ends of the yarn connected by the operator, the trip mechanism reset and the winding may continue.

lVhile I'have described my invention as takin'ge particular form, it will'be understood that the various parts may be changed without departing from the spirit'thereof, and hence I do notyliinit.myself to the .pr' cise construction set forth, but consider that I am at liberty to meke sueh changes"and alterations as fairly come Within the scope of the appended claims.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent is LA tangle arrester including an arm having an aperture through one end Whereby it may be adjustalfly mounted on a coning machine, a clamping plate removably secured to the other end of the arm, a holder clamped between the plate and the end of the arm, and a back, having a plurality of pins extending therei',roni, secured to the holder.

2. A tangle arrester including an arn'r other end of the arm, an extension having one endheld between vthe clamping plate and the arm, a holder on the other end of the ent'ensiome back in the holder, and a plurality of bent pins extending from the back.

3. A tangle arrester IDClHCllDg QH arm having an aperture through oneend whereby it may be adjustably mounted on a coning machine,'a clamping plate bolted to'the other end of the arm, an extension having one end 'held between the clamping plate and the arm, a holder on the other end of the'extension, a back in the holder a plurality of bent p nsextendlng from the back,

and a yarn guide on the holder.

In testimony whereof I have signed my name to this specification.
